"Train C2551, please close the door." At 6:00 on the first day, the C2551 "Fuxing" Multiple unit slowly drove out of Beijing South railway station, passed the Beijing Tianjin intercity, and headed for Binhai, Tianjin, a hundred kilometers away. On the same day, the Beijing Tianjin intercity railway reached its 15th anniversary and transported a total of 340 million passengers. The Beijing Tianjin intercity railway has a total length of 120 kilometers and is an important component of the national mid to long term railway network planning for the Bohai Rim intercity passenger transportation system. It is also the first high-speed railway in China with a designed speed of 350 kilometers per hour. On August 1, 2008, the Beijing Tianjin Intercity Railway was opened. The Beijing South railway station, the departure station, and Tianjin railway station, the terminal station, were officially put into use after reconstruction. A fast and comfortable rail transit mode was established between Beijing and Tianjin. Fuxing Multiple unit is running on the Beijing–Tianjin intercity railway line.

Passengers can reach the Binhai railway station within one hour as soon as possible from the south of Beijing, promoting the acceleration of the formation of the scientific and creative industrial chain of "Beijing R&D, Tianjin manufacturing". Wang Manman, who lives in Wuqing, Tianjin, takes the Beijing Tianjin intercity train to work in Beijing every day. The fastest journey is only over 20 minutes, and during the morning rush hour from 6 to 9 o'clock, there are up to 11 trains that allow her to "come and go". With the increase of passenger flow, the Beijing Tianjin intercity bus gradually operates in a "public transportation" manner. The number of daily trains has increased from 47 to 128, and the shortest departure interval has been shortened from 15 minutes to 3 minutes. According to the statistics of China Railway Beijing Group Co., Ltd., 340 million passengers have been transported between Beijing and Tianjin in the past 15 years. The changes between Beijing and Tianjin are a microcosm of China's high-speed rail development. As of June 2022, China's normalized high-speed railway operating at a speed of 350 kilometers per hour has a mileage of nearly 3200 kilometers; At the end of 2022, the operating mileage of high-speed rail was 42000 kilometers, firmly ranking first in the world. High speed railways have changed people's work and lifestyle, expanding the resource allocation space for various production factors, "said Cheng Shidong, director of the Urban Transportation Center of the Comprehensive Transportation Research Institute of the National Development and Reform Commission. Around Wuqing railway station, the old crop land has become a "new business district", which receives tens of millions of consumers from Beijing and Tianjin every year. "The train stopped for a few minutes, making great changes in Wuqing District." Yuan Xiwei, a staff member of the "New Business District" special work headquarters in Wuqing District, said that the potential of consumption and the spark of creation flowed between Beijing and Tianjin.
